Tinamus guttatus


There are four specimens from two localities in BioMap that allegedly were collected in the Pacific lowlands of Choco and Nariño, which clearly are erroneous records in the database. These records were excluded when modelling the distribution of this species. In spite of that, the habitat suitability model generated in Maxent showed extensive areas in the Pacific region that are suitable in climatic terms for the species. Since it is well established this region is not occupied by the species, those areas were removed from the potential distribution map.

Assuming that the distribution of the species may have filled the complete climatic model generated, its distribution today in remnants of forest is about 444,424 km2, which corresponds to a loss of 12 % of its potential original distribution due to deforestation.


Regularized training gain is 0.271, training AUC is 0.799, unregularized training gain is 0.480.
